RUNG FIXING STRUCTURE, STEPLADDER PROVIDED WITH THE SAME, AND MANUFACTURING METHOD FOR RUNG FIXING STRUCTURE
PROBLEM TO BE SOLVED: To provide a simple structure for fixing a rung securely on a support post and enhance productivity, when at least a part of the support post is inclined to a direction orthogonal to an axial direction of the rung.SOLUTION: A rung fixing structure is for fixing ends of a rung 4 to a pair of support posts 3, the rung being spanned between the pair of support posts 3. The support post 3 includes an inclined part 3b that inclines with regard to a direction orthogonal to an axial direction of the rung 4, and the inclined part 3b includes a perpendicular surface part 31 that forms, on both inner and outer surfaces of the support post 3, support surfaces (31x, 31y) orthogonal to the axial direction of the rung 4 when the rung 4 is spanned between the pair of support posts 3 with both ends of the rung 4 fixed on the support posts. The rung 4 includes a body part 14 that forms a first sandwiching surface 21 coming into contact with the inner support surface 31x as an edge surface on both ends in the axial direction, and a flange part 15 that forms a second sandwiching surface 22 opposite the first sandwiching surface 21 and coming into contact with the outer support surface 31y, and is pressed against and sandwiches the perpendicular surface part 31 along with the body part 14.SELECTED DRAWING: Figure 12
【課題】支柱の少なくとも一部が踏桟の軸方向に垂直な方向に対して傾斜している構成において、簡単な構造により、踏桟を支柱に対して確実に固定させ、生産性を向上させる。【解決手段】一対の支柱３と、一対の支柱３間に横架される踏桟４とを備え、踏桟４の端部を支柱３に固定させる踏桟の固定構造であって、支柱３は、踏桟４の軸方向に垂直な方向に対して傾斜した傾斜部３ｂを有し、傾斜部３ｂは、踏桟４の端部が固定される部分として、一対の支柱３間に横架された状態の踏桟４の軸方向に対して垂直な支持面（３１ｘ、３１ｙ）を支柱３の内外両側に形成する垂直面部３１を含み、踏桟４は、その軸方向の両側の端面として内側支持面３１ｘに接触する第１挟持面２１を形成する本体部１４と、第１挟持面２１に対向するとともに外側支持面３１ｙに接触する第２挟持面２２を形成し、本体部１４とともに垂直面部３１を圧接挟持する鍔部１５とを有する。【選択図】図１２
